幽門螺杆菌各國流行率和胃病沒有相關係數，世界上超過一半的人口帶幽門螺杆菌，別再信那個諾獎者謊言了

世界上超過一半的人口受到感染。

幽門螺杆菌感染的流行率在全球範圍內因社會經濟因素和衛生水平而異。 研究人員對 1970 年至 2016 年的 184 項研究進行了薈萃分析，以檢查 62 個不同國家不同時期的幽門螺杆菌患病率。

結果如下：

世界上超過一半的人口受到感染。

盡管美國和澳大利亞的幽門螺杆菌患病率較低（分別為 35.6% 和 24.6%），但它們的原住民人口患病率很高（阿拉斯加原住民為 74.8%，西澳大利亞原住民為 76.0%）。

患病率最高的地區是非洲（70.1%）、南美洲（69.4%）和西亞（66.6%）； 患病率最低的地區是大洋洲 (24.4%)、西歐 (34.3%) 和北美 (37.1%)。

患病率最高的國家是尼日利亞（87.7%）、葡萄牙（86.4%）和愛沙尼亞（82.5%）； 患病率最低的國家是瑞士 (18.9%)、丹麥 (22.1%) 和新西蘭 (24.0%)。

比較 1970-1999 年和 2000-2016 年期間，幽門螺杆菌患病率在歐洲（48.8% 至 39.8%）和北美（42.4% 至 26.6%）有所下降，但在西亞（53.6% 至 54.3%）保持不變 和拉丁美洲/加勒比地區（62.8% 至 60.2%）。

據估計，2015 年全球幽門螺杆菌感染人數為 44 億人。

Global Prevalence of Helicobacter pylori

More than half of the world's population is infected.

The prevalence of Helicobacter pylori infection varies globally according to socioeconomic factors and levels of hygiene. Investigators performed a meta-analysis of 184 studies from 1970 to 2016 to examine H. pylori prevalence in 62 different countries at different times.

Results were as follows:

More than half of the world's population is infected.

Whereas the U.S. and Australia have a low prevalence of H. pylori (35.6% and 24.6%, respectively) their indigenous populations have a high prevalence (74.8% in indigenous Alaskans and 76.0% in Western Australia indigenous populations).

The regions with the highest prevalence were Africa (70.1%), South America (69.4%), and Western Asia (66.6%); regions with the lowest prevalence were Oceana (24.4%), Western Europe (34.3%), and North America (37.1%).

Countries with the highest prevalence were Nigeria (87.7%), Portugal (86.4%), and Estonia (82.5%); countries with the lowest prevalence were Switzerland (18.9%), Denmark (22.1%), and New Zealand (24.0%).

Comparing the periods of 1970–1999 and 2000–2016, H. pylori prevalence decreased in Europe (48.8% to 39.8%) and North America (42.4% to 26.6%), but remained unchanged in Western Asia (53.6% to 54.3%) and Latin America/Caribbean (62.8% to 60.2%).

The global prevalence of H. pylori in 2015 was estimated to be 4.4 billion people.
